Recently our country highly evaluate cultural value of modern construction. Before and after Japanese imperial period, diplomatic equipment, commerce equipment and brand-new modern construction of Japan and Western came into our country coercively. Especially, modern construction placed in center of the city, as previously stated, was a construction field of historical disgrace. So it leaves alone or transforms to high technology because of well located. Selctive reception of the past makes difficult to know about rightful modem, furthermore it is difficult to expect rightful future. Accordingly, I write this. paper for the purpose of presenting the space application blueprint of 'Jung Myung Jeon' of modern construction designated as the cultural properties in Seoul. According to the project, 'Jung Myung Jeon' will do a role as the keyword which is important connects a past and a present time it presents. Then modern construction 'Jung Myung Jeon' which has a culture value will develop continuous with the city.

In general, under the concept of unit load, Automated Storage/Retrieval Systems (AS/RS) have the rack of equal sized cells. However, they are inadequate and inefficient meeting the various sizes of customers' demands in today's business environment. Higher utilization and flexibility of warehouse storage can be achieved by using AS/RS with tile rack of modularized cell. In this paper, the model of AS/RS with the rack of modularized cell is proposed, and the effectiveness of proposed model is presented by way of numerical examples. The model developed in this research, as one type of AS/RS that is more flexible to the size and has higher space utilization than those of existing rack structure, could every useful for the storage of heterogeneous unit load sizes.

The problem of energy consumption is more serious in university buildings than primary, middle and high school buildings. Because university buildings have generally heating and cooling systems, and various incidental facilities. In university, the library is one of the building that many people use and the most energy is spent. So, investigation on energy saving is very important and urgent. This study aims finally to present the guideline for low-energy design of University library by aiding a designer to select best solution in the side of energy-saving. In this paper, composition of space, utilization schedule and performance of construction materials are grasped, some primary factors that effect to energy saving are analyzed by energy simulation. The result of this study is as follows; First, the subject library has more cooling load than heating load because of cooling load generated during middle season. Second, green roofs is the most effective to heating load saving, but not to cooling energy. Third, outdoor air cooling is the most effective to cooling energy saving among the investigated strategies included in this study.

In recent years, the change of urban function and the decrease in birth rate have given rise to merge, abolition and relocation of the existing building in cities. This study explores the possibilities for various land utilizations of relocated urban sites. In doing so, it compares the development methods and the utilization pattern between home and abroad. It analyses the land use categories and the development methodologies of 4 relocated urban sites happened in Seoul and 4 foreign sites. In addition, it analyzes the land utilization after relocation, development principals, area, building usage and changes in land use regulation. Finally, it proposes the directions for developing relocated site and each of roles among the parties concerned. This study concludes that it is available to exploit the relocated urban sites by the variety of development methodologies, especially in a metropolis like Seoul.

Our country already came into the aging society in 2000, and it will reach the ultimate aging society in 2026. Also it is necessary the architectural proposal to serve the aging society problem. Recently days, it is increased that the aged welfare facilities, and the concern of aged welfare facilities. This study, approaching the charged aged man welfare facilities suggested as an alternative about the increase of aged man and the aged man problem in architectural and environmental aspect, investigated about the overall environment from the establishment of the charged welfare facilities to indoor space on the basis of the satisfaction degree and requiring condition of users through the estimation after residing. Thus this study is purposed to insist importance about analysis the aged welfare facilities and dwelling conscious.

The primary purpose of this study is to suggest the policy for the effective utilization of empty classrooms in elementary school. The empty classroom in this study means the classroom that is not used now since the number of students decreases, but can be usable for other needs in future. The following results are obtained through this survey; 1) about forty percent of classrooms are empty classrooms, 2) the ratio of empty classrooms is higher in urban area than rural area, 3) the smaller the size of classroom is, the higher the ratio is, and 4) 56.5% of the schools have one to three empty classrooms and 30.0% have four to six empty classrooms. In conclusion it is suggested that 1) the reutilization plan of empty classrooms be established according to particular situation of each school, 2) the government develop the guidelines for reutilization and administrative procedures for renewal, 3) the reutilization plan be established from the view point of the quality improvement of schooling, and 4) the enlargement and rearranagemt of learning space be considerd when reutilization is planned.

As the space of the wind power generator stator end is limited, it is difficult for us to place the inner evaporative cooling system in it. We use the non-overlapping concentrated windings scheme to solve the placing and cooling problem. The characteristic of a 5MW direct-driven permanent magnet generator with non-overlapping concentrated windings were analyzed under no-load, rating-load and short-circuit by (Finite Element Method) FEM for verification of design. We studied the connection methods of the stator windings and designed the end connection member. The heat dissipation of the stator end was simulated by FEM, the result showed that the end cooling could satisfy the wind generator operation needs. These results show that the direct-driven permanent magnet wind power generators with non-overlapping concentrated windings and inner evaporative cooling system can solve the cooling problem of wind power generator, and obtain good performance at the same time.

Community facilities in apartment complex have been developed through construction companies' needs for housing development and differentiation combined with a intense marketing competition among housing construction companies. But, It is the fact that the construction companies have planned the community facilities without considering on residents' needs for housing environmental amenity and preference. Therefore, this study investigated the space composition and the present usage of community facilities and surveyed to get concrete information regarding the residents' satisfaction with the proposed community facilities plan. It is the conclusion that the residents request a convenient and comfortable facilities similar level with those in the outside sports complex and the operating programs.

Opportunistic spectrum access (OSA) allows unlicensed users to share licensed spectrum in space and time with no or little interference to primary users, with bring new research challenges in MAC design. We propose a cognitive MAC protocol using statistical channel utilization information and selecting appropriate spectrum hole for multi-channel data transmission. The protocol based on the CSMA/CA, exploits statistics of spectrum usage for decision making on channel access.
